Answer:
Step-by-step explanation:
She needs 12 pizzas
x + y = 12
She also can't spend more than 180 dollars.
8x + 11y < 180 She can get all 12 pizzas and have the bill come to 132 dollars
11 * 12 = 132
She could really be kind to her pocket book and get all cheese pizzas
8*12 = 96 which saves her 36 dollars.
So any number of either kind will do.
(0,12) = 132
(1,11) = 8*1 + 11*11 = 129
and so on down the line
For the subtracting fractions, I would just make them into improper fractions (examples: 6/4, 5/3). To do that, you multiply whole number by the numerator (number on top of fraction), then add the denominator (number at the bottom), and finally, leaving the denominator as is.
Then make them have the same denominator. you might have to multiply or divide in order to match the denominators. then you may add or subtract straight across. NEVER change the denominator.
note: you might be required to make the improper fractions into mixed (ex: 4 1/2)
With multiplying, just multiply across (numerator × numerator, and denominator × denominator)
Answer:
3 2/4
Step-by-step explanation:
2 3/4 = 11/4
11/4 + 3/4 = 14/4
14/4 = 3 2/4
Answer:
C. Bottling plant B (with 175,000 sports drinks per day), because the daily mean will be closer to 20 fluid ounces with more sports drinks in the sample.
Step-by-step explanation:
The general rule is that the larger the sample, the closer the sample mean will be to the population mean. This happens because the standard deviation of our sample is given by the following formula:
![s = \frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
In which
is the standard deviation of the mean volume of all of this type of sports drinks and
is the size of the sample. So as
increases, the less variation there will be, and the closer the sample mean will be to the population mean, that is, the closer the population mean is going to be closer to a mean volue of 20 fluid ounces.
So, the correct answer is:
C. Bottling plant B (with 175,000 sports drinks per day), because the daily mean will be closer to 20 fluid ounces with more sports drinks in the sample.
